Katie Dishes on Tom and Ariana’s Affair — Did They Do More Than Kiss? (VIDEO)

On this week's episode of Vanderpump Rules, Tom Sandoval finally comes clean to Kristen Doute about having made out with Ariana Madix in the Golden Nugget pool in Las Vegas. But is making out really all that they did?

Katie Maloney appears on Watch What Happens Live this week, and a viewer asks Katie if she thinks Ariana and Tom might have actually had sex, rather than just making out in Vegas.

"If we're gonna be honest here, I truly believe that there was a little more that happened — there was at least some heavy petting happening," Katie replies. "The only people that are going to know are the two of them and god."

"They stand by that they just made out, and at least they're admitting to something, so I'm just gonna stand by that," Katie concludes. There's a lot of standing going on here.

But Andy doesn't quite like all that Katie has to say. "Please don't bring god into this," Andy quips.

And so the question remains: Did Tom sleep with Ariana, or didn't he? Katie doesn't appear to know, but it's certainly interesting that Katie has her doubts about whether the making-out story is entirely honest.

Do you think Tom and Ariana slept together, or did they just make out?
